The object of the invention is a particular development of the holding devices for the supply.

This development consists in hinging the holding pegs for the supply bobbins on their carriers in such a fashion that the aforementioned pegs are in a horizontal position when receiving the bobbin and that they are automatically transferred to the vertical unwinding position.

The invention is best illustrated by .the following description of two embodiments thereof, in conjunction with. the accompanying drawings, wherein Fig. 1 is a sectional view across one of the bobbin holding devices having a vertical shaft and pivoted pegs,

Fig. 2 is a front elevation thereof, I

Fig. 3 is a plan view of Fig. 2,

Fig. 4 is a horizontal sectional view of Fig. 1,

Fig. 5 is a sectional view with certain parts in elevation of the charging mechanism for the bobbin holders, I

Fig. 6 is a front elevation of the machine incorporating bobbin holding devices in accordance with the instant invention.

Fig. 7 is a plan view of Fig. 6, and

Fig. 8 is a sectional view across a different embodiment of a bobbin holding device in which the bobbin holding device is mounted on a horizontal shaft parallel to the axis of the bobbin being shifted onto the holder.

Figures 1 to '7 show one embodiment of the invention in different views and partly in cross section. In these figures, 2 is a supply bobbin to be unwound, 2a is a supply bobbin tube, 24k are holding pegs for the supply bobbins and 211 their carrier which may rotate on a vertical shaft 212, as shown in Figs. 1 to 7. In a second embodiment of the invention, shown in Fig. 8, the carrier 211 rotates on the horizontally disposed shaft 212, parallel to the axis of the bobbin.

In both embodiments, thebobbin peg 24k is connected by a hinge 213 to the carrier 211 which in turn is rotatable around' a shaft 212 in such a fashion that it can be made to change its position by sweeping through an angle of say 90 degrees.

In Figs. 1-7- a head 221 is'rotatably mounted upon a vertical axis 212.- Pegs 241:: are pivoted to the head by pins 213, so that the pegs can swing from a radial charging position to an unwinding position parallel to the axis. Fig. 8 is similar except that the axis 212 is horizontal and the pegs 247s are parallel to the axis in the charging position and radial in the unwinding position. In each case, the bobbin holder, is so guided in the support 214 which carries the axis 212 that the swinging pegs engage a surface 215 of the support up to, a point where each peg in succession is to be swung inward. tobring the bobbin'which has been received into unwinding position (Fig. 1), or to assume the position for receiving a bobbin (Fig. 8).

For this purpose the support 214 has an inclined cam surface 216 by which the pegs are successively automatically brought into a vertical position, parallel to the axis 212, in Fig. 1, and perpendicular thereto in Fig. 8. In order to provide a positive guidance for the other pegs not in the displaced position, the support 214 is provided with a guide plate 217, so that the pegs cannot tilt over, particularly in the embodiment shown in Fig. 8. All of the supports 214 on one side of the winding machine, or a group of such supports, can be mounted upon a common frame bar 218 and accurately adjusted thereon.

For the purpose of advancing the bobbin holders, the hub 211 of each holder may have secured to it a shifting star 219, which also has the notches for the centering spring 220 which-serves to accurately position the pegs in the receiving position and the mounted bobbins in the unwinding position.

The advancement of the bobbin holder can be performed in the same way as described inthe aforesaid copending applications, by means of a deflector 15k (Figs. 5-7), or deflectorswhich come into engagement with the shifting star 219.

The shifting of the bobbins which have been brought by the conveyor into charging position in the manner described in the aforesaid copending application onto the pegs 24k can be accomplished by the mechanism, including the shifter 18, shown in the copending application, Serial No. 633,196. In the embodiment shown in Figs. 5-8 it is assumed that the shifter 18 is moved back and forth by a toothed segment 21 to shift the bobbin from the conveyor onto the peg of the bobbin holder which stands in receiving position.

In all the embodiments shown in Figs. 18, the guide plate 217 can serve additionally as the tube stripper, that is, to strip ofithe empty cop tubes from the pegs 24k after the unwinding operation is co c uded.

' by the rotation of said head.
